Summary of Significant Accounting Policies [Abstract]

New Accounting Pronouncements Recently Adopted

Revenue Recognition

Effective April 1, 2018, the Company adopted ASC 606 using the full retrospective transition method. Under this method, the Company adjusted its revised consolidated financial statements (see Note 2). ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract; (iii) determines the transaction price; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are distinct performance obligations. See Note 4 for additional discussion of the adoption of ASC 606 and the impact on the Company’s financial statements.

Financial Instruments

In January 2016, the Financial Accounting Standards Board (“FASB”) issued guidance that amends the classification and measurement of financial instruments. Changes to the current guidance primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the update clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This guidance was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company applied the amendments in the new guidance by means of a cumulative-effect adjustment of $746,000, net of tax, to the opening balance of retained earnings on April 1, 2018. Short-term investments are recorded at fair value with $89,000 of unrealized gain recorded as a component of general and administrative expense for the year ended March 31, 2019.

Modifications to Share-Based Payment Awards

In May 2017, the FASB issued guidance to provide clarity and reduce (i) the diversity in practice and (ii) the cost and complexity when applying the accounting guidance for equity-based compensation to a change to the terms or conditions of a share-based payment award. This update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. This guidance was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 with early adoption permitted. This guidance should be applied prospectively to an award modified on or after that adoption date. The adoption of this guidance on April 1, 2018 did not have any impact on the Company’s consolidated financial statements.

Business Combinations

In January 2017, the FASB issued guidance which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new guidance was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. A reporting entity should apply the amendment prospectively. The adoption of this guidance on April 1, 2018 did not have any impact on the Company’s consolidated financial statements.

Goodwill Impairment

In January 2017, the FASB issued guidance which simplifies the test for goodwill impairment. This standard eliminates Step 2 from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the goodwill carrying amount exceeds the reporting unit’s fair value. This guidance is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. This guidance must be applied on a prospective basis. The early adoption of this guidance on January 1, 2019 did not have any impact on the Company’s consolidated financial statements.

Derivatives and Hedging

In August 2017, the FASB issued guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments in this update also make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the guidance allows for early adoption in any interim period after issuance of the update. The early adoption of this guidance on January 1, 2019 did not have any impact on the Company’s consolidated financial statements.

Improvements to Nonemployee Share-based Payment Accounting

In June 2018, the FASB issued guidance that expands the scope of ASC 718, Compensation—Stock Compensation (which previously only included share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The amendments in this guidance are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than a company’s adoption date of ASC 606. The early adoption of this guidance on January 1, 2019 did not have any impact on the Company’s consolidated financial statements.

Reporting Comprehensive Income

In February 2018, the FASB issued guidance that permits, but does not require, companies to reclassify the stranded tax effects of the Tax Cuts and Jobs Act (the “Act”) on items within accumulated other comprehensive income to retained earnings. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The early adoption of this guidance on January 1, 2019 did not have any impact on the Company’s consolidated financial statements.

New Accounting Pronouncements Not Yet Adopted

Leases

In February 2016, the FASB issued new guidance that requires balance sheet recognition of a right-of-use asset and lease liability by lessees for all leases, other than leases with a term of 12 months or less if the short-term lease exclusion expedient is elected. The new guidance also requires new disclosures providing additional qualitative and quantitative information about the amounts recorded in the financial statements. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new guidance requires a modified retrospective approach with optional practical expedients. The FASB provided entities with an additional transition method, which allows an entity to apply this guidance as of the beginning of the period of adoption instead of the beginning of the earliest comparative period presented in the entity’s financial statements.

The Company will adopt this guidance on April 1, 2019 using the additional transition method. The Company will be electing certain practical expedients permitted under the transition guidance, including the package of practical expedients, which will allow the Company not to reassess lease classification for leases that commenced prior to the adoption date. The Company will also be exempting leases with an initial term of 12 months or less from balance sheet recognition and, for all classes of assets, combining non-lease components with lease components.

The Company anticipates the adoption of this new guidance will result in recognition of additional lease liabilities of approximately $53 million and corresponding right-of-use assets of approximately $51 million, which is net of $2 million in deferred rent currently included in other liabilities in the accompanying consolidated balance sheet, due to the Company’s recognition of all operating lease assets and liabilities on the consolidated balance sheet. The adoption of the new guidance will not have a material impact on the Company’s rent expense and consolidated statement of cash flows. However, the Company has material nonfunctional currency leases that could have a material impact on the Company’s consolidated statement of operations. As required for other monetary liabilities, lessees shall remeasure a foreign currency-denominated lease liability using the exchange rate at each reporting date, but the right-of-use assets are nonmonetary assets measured at historical rates, which are not affected by subsequent changes in the exchange rates.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued an accounting pronouncement related to the measurement of credit losses on financial instruments. This pronouncement, along with a subsequent ASUs issued to clarify certain provisions of the new guidance, changes the impairment model for most financial assets and will require the use of an “expected loss” model for instruments measured at amortized cost. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. The Company plans to adopt this pronouncement for its fiscal year beginning April 1, 2020. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements, as well as any impacts on its business processes, systems and internal controls.

Fair Value Measurements

In August 2018, the FASB issued guidance, which changes the disclosure requirements for fair value measurements by removing, adding and modifying certain disclosures. The standard is effective for financial statements issued for fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Motorcar Parts of America, Inc. and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated.

Segment Reporting

Pursuant to the guidance provided under the FASB ASC for segment reporting, the Company has identified its chief operating decision maker (“CODM”), reviewed the documents used by the CODM, and understands how such documents are used by the CODM to make financial and operating decisions. The Company has determined through this review process that due to recent acquisitions, its business comprises three separate operating segments. Two of the operating segments meet all of the aggregation criteria, and will thus be aggregated. The remaining operating segment does not meet the quantitative thresholds for individual disclosure. Since this immaterial operating segment meets the aggregation criteria of ASC 280, the Company has combined its operating segments into a single reportable segment.

Cash and Cash Equivalents

Cash primarily consists of cash on hand and bank deposits. Cash equivalents consist of money market funds. The Company considers all highly liquid investments purchased with an original or remaining maturity of less than three months at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained with various financial institutions.

Accounts Receivable

The allowance for doubtful accounts is developed based upon several factors including customer credit quality, historical write-off experience and any known specific issues or disputes which exist as of the balance sheet date. Accounts receivable are written off only when all collection attempts have failed. The Company does not require collateral for accounts receivable.

The Company has receivable discount programs that have been established with certain major customers and their respective banks. Under these programs, the Company has the option to sell those customers’ receivables to those banks at a discount to be agreed upon at the time the receivables are sold. Once the customer chooses which outstanding invoices are going to be made available for discounting, the Company can accept or decline the bundle of invoices provided. The receivable discount programs are non-recourse, and funds cannot be reclaimed by the customer or its bank after the related invoices have been discounted.

Inventory

Inventory is comprised of (i) Used Core and component raw materials, (ii) work-in-process, (iii) remanufactured finished goods and purchased finished goods.

Used Core, component raw materials, and purchased finished goods are stated at the lower of average cost or net realizable value.

Work-in-process is in various stages of production and is valued at the average cost of Used Cores and components issued to work orders still open in work-in-process. Historically, work-in-process inventory has not been material compared to the total inventory balance.

The cost of remanufactured finished goods includes the Used Core cost, and component raw materials, and allocations of labor and variable and fixed overhead costs. The allocations of labor and variable and fixed overhead costs are based on the actual use of the production facilities over the prior twelve months which approximates normal capacity. This method prevents the distortion in allocated labor and overhead costs that would occur during short periods of abnormally low or high production. In addition, the Company excludes certain unallocated overhead such as severance costs, duplicative facility overhead costs, start-up costs, training, and spoilage from the calculation and expenses these unallocated overhead as period costs. Purchased finished goods also include an allocation of fixed overhead costs.

The estimate of net realizable value is subjective and based on management’s judgment and knowledge of current industry demand and management’s projections of industry demand. The estimates may, therefore, be revised if there are changes in the overall market for the Company’s products or market changes that in management’s judgment, impact its ability to sell or liquidate potentially excess or obsolete inventory. Net realizable value is determined at least quarterly as follows:

•

Net realizable value for Used Cores are determined based on current core purchase prices from core brokers to the extent that core purchases in the trailing twelve-month period are significant. The Company purchases Used Cores from core brokers to supplement its yield rates and the under return of Used Cores by customers. The Company also considers the net selling price its customers have agreed to pay for Used Cores that are not returned under its core exchange program to assess whether Used Core cost exceeds Used Core net realization value on a customer by customer basis. The average cost for core buy-backs made from customers are deemed the same as the current recorded value of Used Cores. Any reduction of core value is recorded as cost of goods sold in the period in which the revaluation is identified.

•

The Company records an allowance for potentially excess and obsolete inventory based upon recent sales history, the quantity of inventory on-hand, and a forecast of potential use of the inventory. The Company periodically reviews inventory to identify excess quantities and part numbers that are experiencing a reduction in demand. Any part numbers with quantities identified during this process are reserved for at rates based upon management’s judgment, historical rates, and consideration of possible scrap and liquidation values which may be as high as 100% of cost if no liquidation market exists for the part. As a result of this process and an increase in core inventory on hand, the Company has recorded reserves for excess and obsolete inventory of $11,899,000 and $6,682,000 at March 31, 2019 and 2018, respectively.

The Company records vendor discounts as a reduction of inventories and are recognized as a reduction to cost of sales as the inventories are sold.

Inventory Unreturned

Inventory unreturned represents the Company’s estimate, based on historical data and prospective information provided directly by the customer, of finished goods shipped to customers that the Company expects to be returned, under its general right of return policy, after the balance sheet date. Inventory unreturned includes only the added unit value of a finished good. The return rate is calculated based on expected returns within the normal operating cycle, which is generally one year. As such, the related amounts are classified in current assets. Inventory unreturned is valued in the same manner as the Company’s finished goods inventory.

Contract Assets

Contract assets consists of (i) the core portion of the finished goods shipped to the Company’s customers, (ii) upfront payments to customers in connection with customer contracts, (iii) core premiums paid to customers, and (iv) long-term core inventory deposits.

Remanufactured Cores held at customers’ locations as a part of the finished goods sold to the customer are classified as long-term contract assets. These assets are valued at the lower of cost or net realizable value of Used Cores on hand (See Inventory caption above). For these Remanufactured Cores, the Company expects the finished good containing the Remanufactured Core to be returned under the Company’s general right of return policy or a similar Used Core to be returned to the Company by the customer, under the Company’s core exchange program in each case, for credit. The Remanufactured Core portion of stock adjustment returns and the Used Cores returned by consumers to the Company’s customers but not yet returned to the Company are classified as short-term contract assets until the Company physically receives them during its normal operating cycle, which is generally one year.

Upfront payments to customers represent the marketing allowances, such as sign-on bonuses, slotting fees, and promotional allowances provided by the Company to its customers. These allowances are recognized as an asset and amortized over the appropriate period of time as a reduction of revenue if the Company expects to generate future revenues associated with the upfront payment. If the Company does not expect to generate additional revenue, then the upfront payment is recognized in the consolidated statements of operations when payment occurs as a reduction of revenue. Upfront payments expected to be amortized during the Company’s normal operating cycle, which is generally one year, are classified as short-term contract assets.

Core premiums paid to customers represent the difference between the Remanufactured Core acquisition price purchased from customers generally in connection with new business, and the related Used Core cost, which is treated as an asset and recognized as a reduction of revenue through the later of the date at which related revenue is recognized or the date at which the sales incentive is offered. The Company considers, among other things, the length of its largest ongoing customer relationships, duration of customer contracts, and the average life of vehicles on the road in determining the appropriate period of time over which to amortize these premiums. These core premiums are amortized over a period typically ranging from six to eight years, adjusted for specific circumstances associated with the arrangement. Core premiums are recorded as long-term contract assets. Core premiums expected to be amortized within the Company’s normal operating cycle, which is generally one year, are classified as short-term contract assets.

Long-term core inventory deposits represent the cost of Remanufactured Cores the Company has purchased from customers, which are held by the customers and remain on the customers’ premises. The costs of these Remanufactured Cores were established at the time of the transaction based on the then current cost. The selling value of these Remanufactured Cores was established based on agreed upon amounts with these customers. The Company expects to realize the selling value and the related cost of these Remanufactured Cores should its relationship with a customer end, a possibility that the Company considers remote based on existing long-term customer agreements and historical experience.

Customer Finished Goods Returns Accrual

The customer finished goods returns accrual represents the Company’s estimate of its exposure to customer returns, including warranty returns, under its general right of return policy to allow customers to return items that their end user customers have returned to them and from time to time, stock adjustment returns when the customers’ inventory of certain product lines exceeds the anticipated sales to end-user customers. The customer finished goods returns accrual represents the non-core sales value of the estimated returns and is classified as a current liability due to the expectation that these returns will occur within the normal operating cycle of one year.

Income Taxes

The Company accounts for income taxes using the liability method, which measures deferred income taxes by applying enacted statutory rates in effect at the balance sheet date to the differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. The resulting asset or liability is adjusted to reflect changes in the tax laws as they occur. A valuation allowance is provided to reduce deferred tax assets when it is more likely than not that a portion of the deferred tax asset will not be realized.

The primary components of income tax expense were (i) foreign income taxed at rates that are different from the federal statutory rate, (ii) change in realizability of deferred tax items, (iii) impact of the non-deductible executive compensation under Internal Revenue Code Section 162(m), (iv) income taxes associated with uncertain tax positions, (v) the change in the blended state rate, and (vi) the excess tax benefit relating to share-based compensation.

Realization of deferred tax assets is dependent upon the Company’s ability to generate sufficient future taxable income. Significant judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities and any valuation allowance recorded against the Company’s net deferred tax assets. The Company makes these estimates and judgments about its future taxable income that are based on assumptions that are consistent with the Company’s future plans. A valuation allowance is established when the Company believes it is not more likely than not all or some of a deferred tax assets will be realized. In evaluating the Company’s ability to recover deferred tax assets within the jurisdiction in which they arise, the Company considers all available positive and negative evidence. Deferred tax assets arising primarily as a result of net operating loss carry-forwards and research and development credits in connection with the Company’s recent acquisitions have been offset completely by a valuation allowance due to the uncertainty of their utilization in future periods. Should the actual amount differ from the Company’s estimates, the amount of the valuation allowance could be impacted.

Plant and Equipment

Plant and equipment are stated at cost, less accumulated depreciation. The cost of additions and improvements are capitalized, while maintenance and repairs are charged to expense when incurred. Depreciation is provided on a straight-line basis in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives. Machinery and equipment are depreciated over a range from five to ten years. Office equipment and fixtures are depreciated over a range from three to ten years. Leasehold improvements are depreciated over the lives of the respective leases or the service lives of the leasehold improvements, whichever is shorter. Depreciation of assets recorded under capital leases is included in depreciation expense.

Intangible Assets

The Company’s intangible assets other than goodwill are finite–lived and amortized on a straight-line basis over their respective useful lives. Finite-lived intangible assets are analyzed for impairment when and if indicators of impairment exist. At March 31, 2019, the Company’s intangible assets were $8,431,000, and there were no indicators of impairment.

Goodwill

The Company evaluates goodwill for impairment at least annually during the fourth quarter of each fiscal year or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable. The Company has concluded that there is one reporting unit and therefore, tests goodwill for impairment at the entity level. In testing for goodwill impairment, the Company may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the Company’s qualitative assessment indicates that goodwill impairment is more likely than not, it will proceed with performing the quantitative assessment. If the fair value of the reporting unit exceeds its carrying value, goodwill is not considered impaired. If the carrying value of the reporting unit exceeds its fair value an impairment loss will be recognized for the amount by which the carrying value exceeds its fair value; however, the loss recognized shall not exceed the total amount of goodwill allocated to that reporting unit. The Company completed the required annual testing of goodwill for impairment during the fourth quarter of the year ended March 31, 2019, and determined through the qualitative assessment that its goodwill of $3,205,000 is not impaired.

Debt Issuance Costs

Debt issuance costs include fees and costs incurred to obtain financing. Debt issuance costs related to the Company’s term loans are presented in the balance sheet as a direct deduction from the carrying amount of the term loans. Debt issuance costs related to the Company’s revolving loan are presented in prepaid expenses and other current assets in the accompanying consolidated balance sheets, regardless of whether or not there are any outstanding borrowings under the revolving loan. These fees and costs are amortized using the straight-line method, which approximates the effective interest rate method, over the terms of the related loans and are included in interest expense in the Company’s consolidated statements of operations.

Foreign Currency Translation

For financial reporting purposes, the functional currency of the foreign subsidiaries is the local currency. The assets and liabilities of foreign operations for which the local currency is the functional currency are translated into the U.S. dollar at the exchange rate in effect at the balance sheet date, while revenues and expenses are translated at average exchange rates during the year. The accumulated foreign currency translation adjustment is presented as a component of comprehensive income or loss in the consolidated statements of shareholders’ equity.

Revenue Recognition

Through the Company’s agreements with customers, the Company has a single performance obligation, to fulfill customer orders for automotive goods. Revenue is recognized when obligations under the terms of a contract with its customers are satisfied; generally, this occurs with the transfer of control of its manufactured, remanufactured, or distributed products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Revenue is recognized net of all anticipated returns, including Used Core returns under the core exchange program, marketing allowances, volume discounts, and other forms of variable consideration.

For products shipped free-on-board (“FOB”) shipping point, revenue is recognized on the date of shipment. For products shipped FOB destination, revenues are recognized on the date of delivery.

Bill and hold shipments are shipped out to the customer as ex-works; in which the customer makes arrangements and is responsible for their shipping cost. No freight or shipping costs are accrued for revenue under the terms of shipments made as ex-works.

The Company has a single performance obligation; however, the price of a finished remanufactured product sold to customers is generally comprised of separately invoiced amounts for the Remanufactured Core included in the product (“Remanufactured Core value”) and the unit value. The unit value is recorded as revenue based on the Company’s then current price list, net of applicable discounts and allowances. The Remanufactured Core value is recorded as a net revenue based upon the estimate of Used Cores that will not be returned by the customer for credit. These estimates are subjective and based on management’s judgement and knowledge of historical, current, and projected return rates. As reconciliations are completed with the customers the actual rates at which Used Cores are not being returned may differ from the current estimates. This may result in periodic adjustments of the estimated contract asset and liability amounts recorded and may impact the projected revenue recognition rates used to record the estimated future revenue. These estimates may also be revised if there are changes in contractual arrangements with customers, or changes in business practices. A significant portion of the remanufactured automotive parts sold to customers are replaced by similar Used Cores sent back for credit by customers under the core exchange program (as described in further detail below). The number of Used Cores sent back under the core exchange program is generally limited to the number of similar Remanufactured Cores previously shipped to each customer.

Revenue Recognition — Core Exchange Program

Full price Remanufactured Cores: When remanufactured products are shipped, certain customers are invoiced for the Remanufactured Core value of the product at the full Remanufactured Core sales price. For these Remanufactured Cores, revenue is only recognized based upon an estimate of the rate at which these customers will pay cash for Remanufactured Cores in lieu of sending back similar Used Cores for credits under the core exchange program. The remainder of the full price Remanufactured Core value invoiced to these customers is established as a long-term contract liability rather than being recognized as revenue in the period the products are shipped as the Company expects these Remanufactured Cores to be returned for credit under its core exchange program.

Nominal price Remanufactured Cores: Certain other customers are invoiced for the Remanufactured Core value of the product shipped at a nominal (generally $0.01 or less) Remanufactured Core price. For these nominal Remanufactured Cores, revenue is only recognized based upon an estimate of the rate at which these customers will pay cash for Remanufactured Cores in lieu of sending back similar Used Cores for credits under the core exchange program. Revenue amounts are calculated based on contractually agreed upon pricing for these Remanufactured Cores for which the customers are not returning similar Used Cores. The remainder of the nominal price Remanufactured Core value invoiced to these customers is established as a long-term contract liability rather than being recognized as revenue in the period the products are shipped as the Company expects these Remanufactured Cores to be returned for credit under its core exchange program.

Revenue Recognition; General Right of Return

Customers are allowed to return goods that their end-user customers have returned to them, whether or not the returned item is defective (warranty returns). In addition, under the terms of certain agreements and industry practice, customers from time to time are allowed stock adjustments when their inventory of certain product lines exceeds the anticipated sales to end-user customers (stock adjustment returns). Customers have various contractual rights for stock adjustment returns, which are typically less than 5% of units sold. In some instances, a higher level of returns is allowed in connection with significant restocking orders. In addition, customers are allowed to return goods that their end-user consumers have returned to them. The aggregate returns are generally limited to less than 20% of unit sales.

The allowance for warranty returns is established based on a historical analysis of the level of this type of return as a percentage of total unit sales. Stock adjustment returns do not occur at any specific time during the year, and the expected level of these returns cannot be reasonably estimated based on a historical analysis. The allowance for stock adjustment returns is based on specific customer inventory levels, inventory movements, and information on the estimated timing of stock adjustment returns provided by customers. The return rate for stock adjustments is calculated based on expected returns within the normal operating cycle, which is generally one year.

The unit value of the warranty and stock adjustment returns are treated as reductions of revenue based on the estimations made at the time of the sale. The Remanufactured Core value of warranty and stock adjustment returns are provided for as indicated in the paragraph “Revenue Recognition – Core Exchange Program”.

As is standard in the industry, the Company only accepts returns from on-going customers. If a customer ceases doing business with the Company, it has no further obligation to accept additional product returns from that customer. Similarly, the Company accepts product returns and grants appropriate credits to new customers from the time the new customer relationship is established.

Shipping Costs

The Company includes shipping and handling charges in the gross invoice price to customers and classifies the total amount as revenue. All shipping and handling costs are expensed as cost of sales.

Contract Liability

Contract liability consists of: (i) customer allowances earned, (ii) accrued core payments, (iii) customer core returns accruals, and (iv) customer deposits.

Customer allowances earned includes all marketing allowances provided to customers. Such allowances include sales incentives and concessions. Voluntary marketing allowances related to a single exchange of product are recorded as a reduction of revenues at the time the related revenues are recorded or when such incentives are offered. Other marketing allowances, which may only be applied against future purchases, are recorded as a reduction to revenues in accordance with a schedule set forth in the relevant contract. Sales incentive amounts are recorded based on the value of the incentive provided. See Note 17 for a description of all marketing allowances. Customer allowances earned are considered to be short-term contract liabilities.

Accrued core payments represent the sales price of Remanufactured Cores purchased from customers, generally in connection with new business, which are held by these customers and remain on their premises. The sales price of these Remanufactured Cores will be realized when the Company’s relationship with a customer ends, a possibility that the Company considers remote based on existing long-term customer agreements and historical experience. The payments to be made to customers for purchases of Remanufactured Cores within the Company’s normal operating cycle, which is generally one year, are considered short-term contract liabilities.

Customer core returns accruals represent the full and nominally priced Remanufactured Cores shipped to the Company’s customers. When the Company ships the product, it recognizes an obligation to accept a similar Used Core sent back under the core exchange program based upon the Remanufactured Core price agreed upon by the Company and its customer. The Contract liability related to Used Cores returned by consumers to the Company’s customers but not yet returned to the Company are classified as short-term contract liabilities until the Company physically receives these Used Cores as they are expected to be returned during the Company’s normal operating cycle, which is generally one year.

Customer deposits represent the receipt of prepayments from customers for the obligation to transfer goods or services in the future. The Company classifies these customer deposits as short-term contract liabilities as the Company expects to satisfy these obligations within its normal operating cycle, which generally one year.

Advertising Costs

The Company expenses all advertising costs as incurred. Advertising expenses for the years ended March 31, 2019, 2018 and 2017 were $819,000, $610,000 and $525,000, respectively.

Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share includes the effect, if any, from the potential exercise or conversion of securities, such as stock options and warrants, which would result in the issuance of incremental shares of common stock.

The following presents a reconciliation of basic and diluted net income per share.

	Years Ended March 31,
	2019			2018		2017
				(As Adjusted)		(As Adjusted)
Net (loss) income	$	(7,849,000	)	$	19,264,000	$	38,735,000
Basic shares		18,849,909			18,854,993		18,608,812
Effect of dilutive stock options and warrants		-			659,782		809,894
Diluted shares		18,849,909			19,514,775		19,418,706
Net income per share:
Basic net (loss) income per share	$	(0.42	)	$	1.02	$	2.08
Diluted net (loss) income per share	$	(0.42	)	$	0.99	$	1.99

Potential common shares that would have the effect of increasing diluted net income per share or decreasing diluted net loss per share are considered to be anti-dilutive and as such, these shares are not included in calculating diluted net (loss) income per share. For the years ended March 31, 2019, 2018 and 2017, there were 1,580,299, 448,039, and 293,239, respectively, of potential common shares not included in the calculation of diluted net income per share because their effect was anti-dilutive.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. On an on-going basis, the Company evaluates its estimates, including those related to the carrying amount of plant and equipment; valuation of acquisition-related intangible assets including goodwill, impairment of long-lived assets, valuation and return allowances for receivables, inventories, and deferred income taxes; accrued liabilities, warrant liability, share-based compensation, and litigation and disputes.

The Company uses significant estimates in the calculation of sales returns. These estimates are based on the Company’s historical return rates and an evaluation of estimated sales returns from specific customers.

The Company uses significant estimates in the calculation of the lower of cost or net realizable value of inventory.

The Company’s calculation of inventory reserves involves significant estimates. The basis for the inventory reserve is a comparison of inventory on hand to historical production usage or sales volumes.

The Company uses significant estimates in the calculation of its income tax provision or benefit by using forecasts to estimate whether it will have sufficient future taxable income to realize its deferred tax assets. There can be no assurances that the Company’s taxable income will be sufficient to realize such deferred tax assets.

The Company uses significant estimates in the ongoing calculation of potential liabilities from uncertain tax positions that are more likely than not to occur.

A change in the assumptions used in the estimates for sales returns, inventory reserves and income taxes could result in a difference in the related amounts recorded in the Company’s consolidated financial statements.

Financial Instruments

The carrying amounts of cash, short-term investments, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term nature of these instruments. The carrying amounts of the revolving loan, term loan and other long-term liabilities approximate their fair value based on current rates for instruments with similar characteristics.

Share-Based Payments

The Black-Scholes option-pricing model requires the input of subjective assumptions including the expected volatility of the underlying stock and the expected holding period of the option. These subjective assumptions are based on both historical and other information. Changes in the values assumed and used in the model can materially affect the estimate of fair value.

The following summarizes the Black-Scholes option-pricing model assumptions used to derive the weighted average fair value of the stock options granted during the periods noted.

Credit Risk

The majority of the Company’s sales are to leading automotive aftermarket parts suppliers. Management believes the credit risk with respect to trade accounts receivable is limited due to the Company’s credit evaluation process and the nature of its customers. However, should the Company’s customers experience significant cash flow problems, the Company’s financial position and results of operations could be materially and adversely affected, and the maximum amount of loss that would be incurred would be the outstanding receivable balance, Used Cores expected to be returned by customers, and the value of the Remanufactured Cores held at customers’ locations.

Deferred Compensation Plan

The Company has a deferred compensation plan for certain members of management. The plan allows participants to defer salary and bonuses. The assets of the plan, which are held in a trust and are subject to the claims of the Company’s general creditors under federal and state laws in the event of insolvency, are recorded as short-term investments in the consolidated balance sheets. Consequently, the trust qualifies as a Rabbi trust for income tax purposes. The plan’s assets consist primarily of mutual funds and are recorded at market value with any unrealized gain or loss recorded as general and administrative expense. The Company did not redeem any of its short-term investments for the payment of deferred compensation liabilities during the years ended March 31, 2019 and 2018. The carrying value of plan assets was $3,273,000 and $2,828,000, and deferred compensation liability, which is included in other current liabilities in the accompanying consolidated balance sheets, was $3,273,000 and $2,828,000 at March 31, 2019 and 2018, respectively. During the years ended March 31, 2019, 2018, and 2017, an expense of $113,000, $118,000 and $(14,000), respectively, was recorded for each year related to the deferred compensation plan.
